Estrella Resources continues to unveil the prospectivity of the intrusive igneous complex at its Carr Boyd project near Kalgoorlie in WA. The company says it has discovered more nickel-copper rich sulphides on previously untested ground at the Mossgiel and Gossan Hill prospects with mineralisation showing stark similarities to the geology of its original T5 discovery.

Estrella Resources has hooked onto more nickel sulphides at its flagship Carr Boyd nickel-copper project 80 kilometres northeast of Kalgoorlie in Western Australia. A single diamond drill hole yielded a significant strike of 8.07m grading 4.37 per cent nickel and 0.75 per cent copper within a larger zone of 16.2m running 3.12 per cent nickel and 0.60 per cent copper from 192.35m downhole

Nickel-focused Estrella Resources continues to intersect more nickel-copper sulphides in drilling at its Carr Boyd nickel project 80km north of Kalgoorlie in Western Australia. The company says it has hit a cumulative 17.5m of disseminated and blebby sulphides within a broader zone about 24m wide. The finding comes from 782m down a deep hole targeting below the company’s T5 nickel discovery.

Perth-based nickel explorer Estrella Resources has struck nickel-copper sulphides in the first three step-out holes drilled at its T5 prospect 80km north-east of Kalgoorlie in WA’s Goldfields region. The company says the intercepts show mineralisation continues to the south beyond downhole electromagnetic plates from previous drilling of the prospect at its wholly owned Carr Boyd nickel project.

Estrella Resources has recorded a 17m intersection of semi-massive to disseminated nickel-copper sulphides at its Broonhill deposit, part of the company’s Carr Boyd nickel-copper project near Kalgoorlie, in WA. The company says results show Broonhill remains open along strike, is increasing in scale and a separate deposit to the T5 mineralisation 1.5km to the south.

Estrella Resources has extended its T5 deposit by 300m south after step-out diamond drilling hit semi-massive nickel-copper sulphides. The explorer says its hole, part of the company’s Carr Boyd project in WA’s Goldfields region, intersects 1.8m of semi-massive to globular sulphides from 929m came within a broader 21.2m mineralised zone. Down-hole electromagnetic surveys are set to commence soon at the project.

Estrella Resources says it remains on target to kick off full-scale mining of the company’s 5A resource in early 2023 after further high-grade assays at its Spargoville nickel project near Kambalda in WA. With drilling coming to an end, Estrella will now move to extract between 2000 and 4000 tonnes of material for metallurgical testing. The company says plans to calculate a revised mineral resource estimate will feed into ore reserve and pit optimisation modelling.

Nickel-focused Estrella Resources is becoming increasingly bullish about shifting into production after receiving further high-grade assays from resource drilling at the company’s Spargoville nickel project near Kambalda in WA. Significant results from its latest diamond drilling include 3.45m going 5.46 per cent nickel from 70m, containing a high-grade 1.2m at a stunning 10.85 per cent, 11.12m at 1.68 per cent from 59m and 2.7m at 2.47 per cent from 74m.

Estrella Resources has been buoyed by more positive assay results and the bonus of additional key infrastructure as the company moves towards production at its Spargoville nickel project near Kambalda in WA’s Goldfields. Latest results from resource drilling below the Spargoville 5A deposit include a 6.8m hit going 4.4 per cent nickel from 66.2m including 1.76m at 10.21 per cent.

Estrella Resources has received positive assay results showing multiple nickel intersections at the company’s T5 deposit, part of its wholly owned Carr Boyd project north-east of Kalgoorlie in WA’s Goldfields. The company says the results show mineralisation plunges down and to the south with a clear opportunity at depth where the deposit remains open.

Estrella Resources has announced an upgrade of the nickel resource estimate at its Spargoville project’s 5A deposit, 20km south-west of Kambalda, with most of the resource now in the more confident “measured” category. Estrella is pressing ahead with optimisation work for a definitive feasibility study and is focused on 16 000 tonnes of massive sulphide grading 7.8 per cent nickel below 5A’s existing open pit.

Near-term nickel producer Estrella is one step closer to delivering its much-needed battery metal to the market. Glencore’s Murrin Murrin operation has received a bulk sample of high-grade nickel from the company’s Spargoville 5A project, 20 kilometres south-west of Kambalda. Estrella says its assays have met all the specifications from Glencore and the processing of the sample has begun.

ASX-listed Estrella Resources has run the rule over a promising 5A nickel target at its Spargoville project, 20km south-west of Kambalda in WA’s Goldfields, and has opted for an underground decline operation over open-pit mining. The company will now press full-steam ahead towards restarting the historic mining at Spargoville of nickel – now a much-needed battery metal.

Estrella Resources has identified a slew of fresh targets at its Carr Boyd nickel project near Kalgoorlie following a review of data from its partnership with the CSIRO and results from a recent seismic survey. The company says it has highlighted 30 targets, including 15 with known nickel-copper-platinum group element intersections and another 15 hosting the right geology, but which are yet to be tested.

Estrella Resources’ share price doubled this morning on the back of the company revealing an impending world-first helicopter-borne electromagnetic survey (TargetEM) at its Carr Boyd nickel-copper-PGE project in Western Australia. Given the significant technology and sensitivity upgrades of its new system, Estrella is intensifying its hunt for drill targets that previously evaded detection while using the older technology.

Estrella Resources is evaluating its Carr Boyd project in Western Australia’s Goldfields region for lithium-pegmatite potential associated with a granitic or monzonitic body that intrudes the northern flanks of the mafic-ultramafic nickel host. New interpretations and a recent nickel discovery have highlighted areas of nickel potential and also indicate possible pegmatite-hosted lithium and related mineralisation within the project.

Estrella Resources has utilised a next-generation helicopter-borne electromagnetic geophysical system to identify several new conductor anomalies at its Carr Boyd project in Western Australia’s Goldfields region. Multiple anomalies through a 5km strike length along the Colreavy komatiite have been recognised and, importantly, the “Target EM” system has also identified a new 3km linear zone under cover to the south of the Carr Boyd intrusion.

Estrella Resources has earned pre-qualification in the Timor-Leste Government’s inaugural minerals tender process, opening up a potential pathway for the company to acquire tenure in a region known to host more than 200 mineral occurrences including gold, copper, manganese, silver and chromite. The process appears set to end the region’s dearth of exploration due to a succession of long-standing geopolitical factors.

Interim feasibility work by Estrella Resources has confirmed the viability of a simple decline and two-level underground mine for its 5A nickel deposit at the company’s Spargoville project near Kambalda in WA. Management has estimated the mine’s capital and operating costs at $11 million, which can be represented as $US3.20 ($AU5.60) per pound of nickel produced. The current price is hovering at about $US8.30 (AU$13.30).

Estrella Resources has confirmed the presence of a slew of multiple stacked, fractionating pegmatites during field work at its Carr Boyd project near Kalgoorlie in Western Australia’s Goldfields region. The company says the outcropping pegmatites can be traced for a few hundred metres before going beneath the cover again and a follow-up works program of mapping and sampling is already underway.

Estrella Resources will use a $1.327 million research-and-development tax rebate from the ATO to repay a loan facility, with about $181,000 in surplus cash to be aimed at further exploring its Carr Boyd nickel project in Western Australia’s Goldfields region. The company says it will continue its R&D work into mineralisation genesis and make a further claim at the end of the next financial year.

Estrella Resources’ hunt for manganese in Timor-Leste is heating up, with recent grab samples from riverbeds going as high as 58.4 per cent manganese at the company’s newly-coined Dasidara prospect. Management says geological reconnaissance across its 503.7 square kilometres of ground has defined mineralisation through 30km of strike length as proposals to kick off trenching and drilling are maturing.

Geological mapping and grab sampling by Estrella Resources has stretched its manganese strike out to 47km in Timor-Leste, with some priority samples already crushed and sent back to Perth for expert lab analysis. The company is now weighing up its business case for the potential first-ever manganese exports from the Southeast Asian country formerly known as East Timor.

Estrella Resources has inked a milestone joint venture and royalty deed with Murak Rai Timor (MRT), the State-run mining arm of the Timor-Leste Government, to explore for manganese, copper and gold in that country. Estrella will hold 70 per cent of the newly-formed venture that includes three exploration licenses covering a landholding of 121.5 square metres, with MRT holding 30 per cent.

Estrella Resources is continuing to deliver the goods at its Lautém project in virgin Timor-Leste, with the discovery of new supergene manganese mineralisation exposed from surface at its Sica prospect. The company also received “exceptional” assay results from grab samples taken at several nearby prospects, with grades reaching as high as 57 per cent manganese.

Estrella Resources has applied for four additional exploration and evaluation licenses, identified as containing rich outcropping manganese, in Timor-Leste’s Baucau municipality. The new coastal licenses, which are 8km west of the company’s existing grounds, cover an area of 194.4 square kilometres. If granted, the additional prospects would bring Estrella’s total landholding in the country to nearly 700 square kilometres.

Estrella Resources has locked up four extra exploration and evaluation concessions to kick off Timor-Leste’s newly-instituted 2021 mining code direct grant process. The leases, which are particularly prospective for manganese, sit in the Southeast Asian country’s western Baucau Municipality and add to its four exploration licences, 30km to the north-east, that it picked up last year.

Estrella Resources has revealed high-grade manganese in Timor-Leste just days after nailing down new exploration licenses at its Samalari prospect in the nation’s Baucau Municipality. The site is showing manganese oxide mineralisation along a 1.7km strike zone with widths of up to 5m and early samples have returned impressive hits going up to 53.9 per cent manganese, according to analysis from Australian Laboratory Services.

Global metals-trading giant Glencore has cast its eye across Estrella Resources’ manganese ground in Timor-Leste, where the latter has unveiled high-grade rock-chip assays hitting up to 57 per cent manganese at its Sica and Lalena prospects in the nation’s Lautém Municipality. The results, which highlight the high-grade nature of manganese mineralisation in the largely untapped region, have marked a major step forward for Estrella’s exploration.

Estrella Resources has jagged what the company says is its biggest-ever manganese outcrop in Timor-Leste – a massive supergene zone discovered 500m south of its Samalari prospect during ongoing mapping efforts. The recent find is particularly important due to the sheer scale of the manganese-iron oxides-rich outcrop that has been traced across a 1.7km strike and ranges between 2m and 6m in width.

Estrella Resources has uncovered not one but two supergene manganese discoveries at its Lautém project in Timor-Leste. The reportedly high-grade manganese assets were uncovered using the company’s predictive modelling of its prospective Noni rock formations. Estrella says its Ira Miri and Sica discoveries are around 4.5km apart just outside the town of Lautém and feature some of the highest-grade rock chips sampled to date.

Amid a grand celebration of the WA ASX-listed small cap company community on Friday night, Larvotto Resources triumphed to take out the coveted Bulls N’ Bears “Peak Performer of the Year” award after achieving a peak share price hike of 993 per cent. Estrella Resources took out the other major award and is the Bulls N' Bears “Runner of the Year”, claiming a 240 per cent share price jump from January to November 2024.

Estrella Resources has received encouraging responses from its first geophysical survey line across its recently discovered Ira Miri manganese zone at Lautém in Timor-Leste, prompting its maiden drilling campaign. The low resistivity anomaly is interpreted as a potential target for supergene manganese and aligns with previously reported outcrop mapped onsite, although more work is required to gauge the potential scale of the anomalism.

Estrella Resources has received some stunning assay results from rock chip sampling from two in-situ supergene manganese discoveries at its Lautém project in Timor-Leste, with grades up to a striking 58.6 per cent manganese. Bulk determinations for detrital material accumulated on valley floors average a whopping 40.1pc manganese.

Estrella Resources has jagged a rich deposit of transported alluvial manganese at its Soru prospect within the company’s Lautém manganese project in Timor-Leste, with visual grades running as high as 95pc. The manganese may have leached from the surrounding hills due to erosion to form a supergene deposit before breaking up and creating a tertiary deposit of boulders and rock fragments across the hillside and in the local creek systems.

Estrella Resources is set to make history in Timor-Leste by launching the country’s first mineral exploration drilling campaign at its Ira Miri, Sica and Lalena manganese prospects. Partnering with experienced in-country operator CoreSearch Minerals, a division of the experienced H2O group, Estrella is investing US$200,000 to mobilise a fully equipped RC and diamond drilling rig into the country’s northwest.

Estrella Resources has notched yet another landmark achievement in Timor-Leste, formally East Timor, announcing the first conversion of permits into exploration licenses under the mineral-rich country’s new mining laws. The newly minted licenses will enable the company to deploy ground-disturbing exploration methods, including all-important maiden drilling campaigns, set to kick-off upon receipt of the nation’s first ever drill rig.

Estrella Resources has inked a landmark deal that could see up to 500 million tonnes of limestone exported from Timor-Leste over five years, targeting South East Asia’s surging industrial minerals demand. The binding agreement with Indonesian group PT Raka Energi Mandiri grants exclusive rights to market and sell Estrella’s high-grade, calcite-rich limestone from its extensive Timor-Leste tenements.

Estrella Resources has launched Timor-Leste’s first modern metallic mineral exploration by drilling its maiden hole at the Ira Miri manganese prospect. In a JV with Murak Rai Timor and CoreSearch, Estrella has mobilised a man-portable rig from Dili to Lautem. The program includes 3000m of diamond and 20,000m of RC drilling across two phases, targeting manganese within the Noni Formation.

Estrella Resources has made a landmark discovery in its maiden exploration program in Timor-Leste, intersecting a thick 6.45m zone of massive manganese oxides just 1.35m below surface at its Ira Miri prospect. In what marks the first modern metallic minerals drillhole sunk in the country, Estrella’s initial diamond hole confirmed high-grade manganese mineralisation right from the outset, which is still open at 7.8m depth.
